LEAsInG' COMB.

Application filed April 20, 1825. Serial No. 24,343,

The object of this invention is the provi sion of a simple, cheap andetlicient leasing comb for use in connection with a ball warper or othermachine.

In th accompanying drawings, Figure 1 is a fragmental side elevation ofa leasing comb embodying the features oi my invention.

Fig. 2 is a fra mental longitudinal sectional View of the comb.

Fig. 3 is a transverse sectional view of the comb showing the comb inits upper position.

4 is a similar view showing the comb in its lower position.

Fig. 5 is a diagrammatic view.

Figs; 6 and 7 are fragmental perspective views corresponding to Figs. 3and 4-, respectively.

A leasing comb embodying the features of this invention may be employedin connection with warpers and other textile machines of various forms.In the diagram constituting Fig. 5, A represents the yarn mass beingformed, and B are guides to which the threads extend from the creel andfrom which the threads pass through the leasing comb G and thence to theyarn mass A. V

The comb C is formed of splits or teeth 1, the lower portions of whichare rigidly secured together and fixed to a structure constituting aback 2. The combis mounted in guides 3 for vertical movement. l/Vhileany preferred means may be employed to raise and lower the comb C, Ihave herein indicated means including a cam at mounted for pivotalmovement on an axis 5. The cam 4- comprises a low portion or notch 6, ahigh portion or notch 7 and an intermediate notch 8, the back 2 beingprovided with a roller 9 arranged to rest in any of said notches. Itwill thus be seen that the comb C may occupy three different positions.

As shown in the drawings, the comb is open at the top for the receptionof threads.

Alternate spaces in the comb are open from v the top to the upper edgeof the back 2. Downward movement of the threads in the other spaces islimited by means of rivets 10 which extend between pairs of splits 1.Upward movement of threads in the last mentioned spaces is limited bylugs 11 which are struck laterally from one split of each pair andextend into an opening 12 in the other split of each pair. The uppersurface .ofeach lug 11 is downwardly inclined'so as to permit a threadto slip down past it.

The lower edge of the lug is approximately horizontal and, as stated,extends into the opening -12 and thus bridges the space be tween thesplits and thereby limits upward movement of a thread which has passedbelow the lug. 'VVhen the comb is in its middle position all the threadsextend between the horizontal planes of the rivets 10 and lugs 11. asshown in Fig. 5.

The comb C being in its middle position,

the threads extending from the creel may be laid in the comb andattached to the yarn beam or other receiving yarn container. When it isdeslred to form a lease in the threads the operative turns the cam i tothe comb in its upper position, as shown in Fig. 3. The rivets 10thereby .raise the threads which were previously depressed by the lugs11 so as to elevate said threads above the others, as indicated in Fig.3. In

to the shed thus formed a lease rod E is in serted. The lease rods arethen replaced with the usual tapes, thus completing theleasing-operation. The comb is then restored to its normal middleposition as shown in Fig. 5.

It will beis'een that the leasing comb herein disclosed is very simplein construction, cheap to manufacture, and efficient in operation,

I claim as my invention: 7

1. An open-top leasing comb having, in combination, sheet metal splitsand a back, the splits being secured to the back, the thread-receivingspaces between the teeth being open at the top, rivets securing saidsplits together in pairs at points above the back, said rivets servingto limit downward movement of the threads in alternate spaces, the otherspaces being unobstructed to permit the threads in said last-mentionedspaces to descend below the plane of said rivets, one split of each ofsaid pairs having a ri gid lug struck iaterally therefrom, which luextends partway into an opening formed in the other split of the pair,the upper side oi": said lug being downwardly inclined to slip down pastit, the lower end 01": said lug serving to bridge the space between saidpair of splits and prevent the thread from moving up past the lug.

2. A. leasing comb having, in combination, sheet metal splits and aback, the splits being secured to the back, the thread-receiving spacesbetween the splits being open at the top, and means securing said splitstogether in pairs at points above the back, said means serving tolimitdownward movement of the threads in alternate spaces, the otherspaces being unobstructed to permit the threads in said last-mentionedspaces to descend below the plane of said limiting means, one split ofeach of said pairs having a rigid lug struck therefrom, which lugextends partway into an opening formed in the other split of the pair,the upper side of said lug being downwardly inclined to slip down pastit, the lower end or said lug serving; to bridge the space between saidpair of splits and prevent the thread from moving up past the lug.

In testimony whereof, I have hereunto afiixed my signature.
